Complete y balancee las dos ecuaciones de las reacciones que se describir en en el siguiente texto la acrópolis de Atenas . Grecia se esta deteriorando lentamente esta hacha de mármol (caco3) el cual reacciona poco a poco con el acido sulfúrico que proviene del aire contaminado y forma una sal, que desaparece luego destruyendo este famoso a partir del aire trióxido de azufre del agua

Does anyone know a lot about how to: - calculate mass of magnesium metal - calculate the actual yield of magnesium oxide - calculate the theoretical yield of mgo - calculate the percent yield of mgo - determine the percent yield of mgo - determine the average percent yield of mgo i had to do an online lab and its asking these questions but i have no idea where to start or how to be able to find these things. i can post the chart of the data from the lab or if you can tell me exactly how i can find each.

How are isotopes of the same chemical element alike? how are they different?

What does a complete balanced chemical equation include? a. exothermic coefficients b. endothermic coefficients c. valence electrons d. molar coefficients
